Gugure! Kokkuri-san is an eccentric comedy centered around the self-proclaimed doll, Kohina Ichimatsu. Her uneventful life goes from plain to absurd when she summons a fox spirit by the name of Kokkuri-san.

Upon meeting the bizarre girl who summoned him, Kokkuri-san is shocked to discover that Kohina not only lives alone, but survives on just cup ramen! Filled with concern for the young girl, he takes it upon himself to ensure that Kohina has proper meals and lives a decent life. Thus begin Kokkuri-san's less-than-hopeful endeavors and their peculiar life together.
